I have several that I have purchased over the years, and I also suggest a 30' one. I keep one in each vehicle. There are a lot of brand name one's out there, and with different ratings. There is also some pretty good recovery "ropes" as well, such as "Bubba Rope". They take up a little more room since you can't roll them up like a strap. A couple of years ago I purchased the "Big Bubba", 1 1/4" x 30' to keep in the truck. It is rated at 52,300. What made me a believer in the rope, was watching a guy with a 3/4, 4x4 pickup "snatch" a medium duty single axle dump truck from a snow bank. I'm sure a larger recovery strap with higher ratings could have done the same. But this sure was impressive to see. If you have ever seen or used a good "recovery/snatch strap or rope, you know what they can do. It is something that you may never use, but sure nice to have if needed. Good luck with your choice.
